Application ld November 10, 1915. Serial No. 60,730.

To all 'whom t may concern.'

Be it known that we, ERNEST 0. LINToN and FRANK J. BLUM, citizens of the United States, residing at Kenosha, in the county of. Kenosha and State 4of Wisconsin, have v then burned under such conditions that there is provided a supply of oxygen suHicient to insure complete' combustion. A fur-l ther andprincipal object of our invention is to so combine the various elements of. the device that there is produced a 'llame of exceedingly high temperature', either oxidizing or reducing ,as desired, and of large volume with a minimum consumption of fuel.

A vfurther object of our invention is -to provide means for readily controlling and adjusting lthe temperature of the coil or retort in which" the fuel is' va orized or gasi fied, and to provide means' or heating such .coil or retort by a non-oxidizing or neutral flame, corrosion of the coil or retort being. thereby avoided. 1

Itis a still further object of'our invention to provide a device of novel mechanical construction for producing 4a gas fromv heavy hydrocarbon fuel and burning the thus-,produced gas' without any deposit ofl carbon either inside or outside thev burner.

' These obj ectswe attain by the construction shown in the accompanying drawings, in which,-

Figure- 1 is an elevation ofthe device,

a control valve 15 from which the oil vpasses lnto a pipe 9, which extends from a considerable distance-into the surrounding air pipe 8, as e. g. live to ten times the -inner 4 iameter of the air pipe 8. This pipe 8y 'passes into the `inside of an open-ended casing 1, preferably cylindrical in shape, and is there continued inthe form of a coil 8" having several convelutions from which coil it is connected by pipe 8, through a return. pipe, to the gas-nozzle.7. The gas-nozzle 7 projects into a burner-tubel2, which is Supported by the spider ring 21 carried by the arms 20 connected tothe casing l. To the gas-nozzle .is secured, at its inner end, an air intake cap 5, having a series of air openings 5'; this cap 5 being in turn secured to a guide-tube 6 surrounding and sliding on' the gas-nozzle 7 The burner tube2, gas-nozzle 7 and perforated cap 5 form a Bunsen burner. The burner-tube 2 has at its outer end a gas bathe 4, preferably constructed, as

shown in Fig. 1, to form an annular pocket or chamber between its inner end portion andthe inner wall of the gas-nozzle 47. A short distance to the rear of this gas baffle 4, whichl serves to-cause a rebound or reflux ofY some of the outwardly flowing mixed gas and air, the' burner tube 2 is provided with a series of rearwardly inclined slots 3, through whichthis -reiuxed' mixture may 'escape and burn within the annular space between the casing 1 and 'burner tube 2 and heat the coil 8 located in this. space.

The l gas issuing from the slots and the Haine resulting from its combustion 'are given a backward whirling motlon, and 'may extend to the rear,` of the casing 1, or as far therein as may be desired. rllhe Aslots 3 are prefer` ably made by cutting, as with a saw, the plane of the saw being at an angle of about 30 to the axis. A circumferential series of such cuts aremade, the planes of the adj oining cuts being at a very obtuse angle to each other. lin practice, we have found that with a casing of live inches internal diameter, and a burner-tube of 2i inches in. diameter, five slots, about 2% inches long and 31g inch wide, inj'each circumferential series and two .of such series extending together over about four inches lengthwise of the pipe are sucient toI produce the eil-'ect desired, which will be later described. An additional sup- Oil under pressure is delivered through the fio spray-pipe 9 into the stream of air under pressure flowing through the pipe 8. The mixed oil and air pass through the coil 8', where they are subject to a temperature sufficient to vaporize or gasify the oil, the coil being heated to such temperature, say from 70W-900o by the combustion of the gas mixture issuing from the slots 3. Ow'- lng to the backward inclination of these slots, the gases and the resulting flame are givenl a rearward whirling motion. The heated mixed gases, with the additional air delivered through pipe 12, flow under high pressure through the gas-nozzle 7, from which'they expand into the burner-tube 2. The main body of the combustible mixture passes out of the endof the burner-tube and burns with a blue iame. The high velocity at which the gases are delivered from 'the pipe 7 causes additional air to be drawn in through the openings 5 in the cap 5. By proper adjustment of the oil and air supply, we are enabled to produce a high velocity blue iame of large volume and are thus enabled to-deliver a large number of heat units at a rapid rate, whereby a very high temperature may beproduced and maintained. We have found in practice that an air pressure of from 25 to 100 pounds per inch may be successfully used.

Theproper temperature of the flame within the space between the burner-tube .2 and casing l may be controlled by sliding the burner-tube toward or from the casing. If it is vmoved rearwardly, as to' the position vshown in full lines, the temperature of this coil-heating llame is increased, as this flame then strikes more or all of the heating coils; by moving the burner-tube farther into' the casing the temperature of the coil-heating flame is reduced, as a smaller number of the heating coils lie within the ame. If the coil 8. begins to show a tinge of red, the

.temperature is becoming too highand the burner pipe is accordingly moved forward and the temperature of the coil reduced. If from the appearance of the main llame or other indications, the oil is not bein lcompletely gasied, the burner pipe is sli backward andthe temperature of the coil thereby increased.

While the main heating ame is an exceedingly hot blue flame, oxidizing. in character, the coil heating liame is non-oxidizing or neutral in character, and therefore has no tendency to oxidize or corrode the heating coil, nor is there any objectionable deposit of carbon or soot. By forcing the voil and vapor through the tube 8 by compressed air, the speed of the mixed gases is such that there is no possibility of any deposit of carbon in the coils 8 and pipe 8. The additional air from pipe 12 assures -a sufficient supply of oxygen and breaks up any possible particles of oil remaining andy makes the mixture perfect. There is thus provided an ample supply of air and the. necessity for aprohibitively large heating coil is obviated.

An exact control of all the conditions essential to the production of complete combustion is therefore provided.

Our burner is available for heating steamboilers, japan kilns, annealing ovens, furnaces for melting metals such as steel or brass, etc.
